An ancient struggle re-erupts on Earth between two extraterrestrial clans, the heroic Autobots and the evil Decepticons, with a clue to the ultimate power held by a young teenager.

Sam Witwicky leaves the Autobots behind for a normal life. But when his mind is filled with cryptic symbols, the Decepticons target him and he is dragged back into the Transformers war.

A long time ago, far away on the planet of Cybertron, a war was being waged between the noble Autobots (led by the wise Optimus Prime) and the devious Decepticons (commanded by the dreaded Megatron) for control over the Allspark, a mystical talisman that would grant unlimited power to whoever possessed it. The Autobots managed to smuggle the Allspark off the planet, but Megatron blasted off in search of it. He eventually tracked it to the planet of Earth (circa 1850), but his reckless desire for power sent him right into the Arctic Ocean, and the sheer cold forced him into a paralyzed state. His body was later found by Captain Archibald Witwicky, and before going into a comatose state Megatron used the last of his energy to engrave a map, showing the location of the Allspark, into the Captain s glasses, and send a transmission to Cybertron. He is then carted away by the Captain s ship. A century later...

Autobots Bummblebee, Rachet, Ironhide and Sideswipe led by Optimus Prime, are back in action taking on the evil Decepticons, who are eager to avenge their recent defeat. The Autobots and Decepticons become involved in a perilous space race between the U.S. and Russia, to reach a hidden Cybertronian spacecraft on the moon and learn its secrets, and once again Sam Witwicky has to come to the aid of his robot friends. New villain, Shockwave, who rules Cybertron, is on the scene while the Autobots and Decepticons continue to battle it out on Earth.
